-# == Class: nova::compute::libvirt
-#
-# Install and manage nova-compute guests managed
-# by libvirt
-#
-# === Parameters:
-#
-# [*libvirt_virt_type*]
-# (optional) Libvirt domain type. Options are: kvm, lxc, qemu, uml, xen
-# Replaces libvirt_type
-# Defaults to 'kvm'
-#
-# [*vncserver_listen*]
-# (optional) IP address on which instance vncservers should listen
-# Defaults to '127.0.0.1'
-#
-# [*migration_support*]
-# (optional) Whether to support virtual machine migration
-# Defaults to false
-#
-# [*libvirt_cpu_mode*]
-# (optional) The libvirt CPU mode to configure. Possible values
-# include custom, host-model, none, host-passthrough.
-# Defaults to 'host-model' if libvirt_virt_type is set to either
-# kvm or qemu, otherwise defaults to 'none'.
-#
-# [*libvirt_disk_cachemodes*]
-# (optional) A list of cachemodes for different disk types, e.g.
-# ["file=directsync", "block=none"]
-# If an empty list is specified, the disk_cachemodes directive
-# will be removed from nova.conf completely.
-# Defaults to an empty list
-#
-# [*libvirt_inject_password*]
-# (optional) Inject the admin password at boot time, without an agent.
-# Defaults to false
-#
-# [*libvirt_inject_key*]
-# (optional) Inject the ssh public key at boot time.
-# Defaults to false
-#
-# [*libvirt_inject_partition*]
-# (optional) The partition to inject to : -2 => disable, -1 => inspect
-# (libguestfs only), 0 => not partitioned, >0 => partition
-# number (integer value)
-# Defaults to -2
-#
-# [*remove_unused_base_images*]
-# (optional) Should unused base images be removed?
-# If undef is specified, remove the line in nova.conf
-# otherwise, use a boolean to remove or not the base images.
-# Defaults to undef
-#
-# [*remove_unused_kernels*]
-# (optional) Should unused kernel images be removed?
-# This is only safe to enable if all compute nodes
-# have been updated to support this option.
-# If undef is specified, remove the line in nova.conf
-# otherwise, use a boolean to remove or not the kernels.
-# Defaults to undef
-#
-# [*remove_unused_resized_minimum_age_seconds*]
-# (optional) Unused resized base images younger
-# than this will not be removed
-# If undef is specified, remove the line in nova.conf
-# otherwise, use a integer or a string to define after
-# how many seconds it will be removed.
-# Defaults to undef
-#
-# [*remove_unused_original_minimum_age_seconds*]
-# (optional) Unused unresized base images younger
-# than this will not be removed
-# If undef is specified, remove the line in nova.conf
-# otherwise, use a integer or a string to define after
-# how many seconds it will be removed.
-# Defaults to undef
-#
-# [*libvirt_service_name*]
-# (optional) libvirt service name.
-# Defaults to $::nova::params::libvirt_service_name
-#
